Dr. M. Andersson

Verified order

Stockholm, Sweden · 12 Apr 2026 · BPC-157

COA matched batch number exactly

Ordered three batches of BPC-157 over four months. Each shipment arrived cold-packed with a COA and the batch numbers cross-checked against the public testing database. Purity reported between 98.7% and 99.2% — consistent with what we measured in-house by HPLC.

London, UK · 2 Apr 2026 · Tirzepatide

Fast UK delivery, clean reconstitution

Discreet packaging, arrived in 48 hours to London. Lyophilised cake was firm, dissolved completely in bac water with no cloudiness. Dose math in IU on the calculator made repeat dosing trivial.

Best documentation I've seen from a supplier

We compared three suppliers as part of a sourcing audit. Regena was the only one with chromatograms, retention times and lab-named COAs published per batch. That's the standard the rest of the industry should meet.

Copenhagen, Denmark · 19 Mar 2026 · Ipamorelin

Good product, customs took an extra day

Product itself is excellent — clean reconstitution, COA available. Customs added 24 hours which is outside Regena's control. Support replied within an hour when I asked for an update.

Birmingham, UK · 10 Mar 2026 · Tesamorelin

Independent lab agreed with stated purity

We sent a sub-sample to an independent lab. Their result was within 0.4% of the published Regena COA. That's a level of transparency you almost never see in research-peptide sourcing.

Berlin, Germany · 27 Feb 2026 · MOTS-c

Cold chain held the whole way

Temperature indicator strip in the package stayed in the green. Vials still chilled on arrival despite a 3-day route. Whoever packs these boxes knows what they're doing.

C. Garcia

Verified order

Madrid, Spain · 14 Feb 2026 · Retatrutide

Hard-to-source compound, well-documented

Retatrutide is genuinely difficult to source with verifiable testing. Regena published the full COA, the lab name, the retention time and the chromatogram peak. That's enough information to trust.

Dr. N. O'Brien

Verified order

Dublin, Ireland · 3 Feb 2026 · GHK-Cu

Consistent batch-to-batch

Four GHK-Cu orders across 18 months. Colour, reconstitution behaviour and reported purity were consistent every time. That consistency is more valuable than a single very-high-purity batch from somewhere else.
